I think it's gonna be Pitt even though the only challenging team they played this year was Ohio State. But no one else in the top teams have really had any tough games yet either. In the last 5 games Pitt has won by an avg. of 29.8 pts per game.
How about Arizona staying #1? Walton was out, they were on the road facing a solid SEC team and they lose by 1 point. Does anyone really believe Pitt is better than Arizona?
I guess we won't really know who is better until March. But chances are that since Arizona lost to an unranked team, they won't be number one this week.
